I was trying to report a weirdness of a long wrap-prefix
with non-nil word-wrap but got a crash.

With emacs -Q, evaluate in *scratch*:

(progn
  (setq word-wrap t wrap-prefix (make-string 120 ?\s))
  (dotimes (i 25) (insert (make-string 120 ?.) "\n")))

Program received signal SIGSEGV, Segmentation fault.
